alright.
Is there any tricks/technique or anything that could help me understand the game more?
b/c I'm seeing people turning like crazy and know where they're going and all. And it seems really hard to do all that with just 2 fingers I assume.
I would like to learn those,and
Thanks.

Hi. In order to train well, play often on sumo and fort servers, listen to advice, be nice to people, feel free to ask questions when in doubt, be active on the forums.
And don't get mad if it will happen that some players will get mad on you for not knowing everything about the game tactics yet.

We use 2 keys for each direction. Means 2 for right and 2 for left which you can press at the same time to make a quick turn.
Some use 3, too, it's a thing of habitude.
And to know where to go: Just play, train, ask, and drink beer.

Yes, you have to use 2 keys if you want to do a quick turn. That is called "double bind".
And you can use other camera instead of default camera for having a larger view. Look for that in esc/player menu/player 1 settings/camera menu.
